In 1967 British astronomer Jocelyn Bell Burnell was left stunned by mysterious pulsing signals she detected coming from outside the solar system.

For months she suggested the signals could be of an extraterrestrial intelligent origin, but they were later proven to be rapidly spinning stars known as pulsars.

However, a new series of mysterious signals, known as Fast Radio Bursts (FRBs), has again got astronomers scratching their heads and wondering if, maybe, we’re picking up alien messages.

‘This extraordinary finding either indicates an as yet unknown or unusual astronomical phenomenon, or it could indicate that this is a vast alien communication network, and the universe is teeming with intelligent life forms,’ says Nigel Watson, author of the UFO Investigations Manual.

‘Every unusual signal from outer space encourages us to wonder if it is from an alien civilisation.

‘Since this signal seems so elusive and hard to interpret then this should be a candidate for further analysis.

Some stars are known to suddenly flare up on occasion. It’s possible that this event could send light through the thick ejected layers of a star’s atmosphere in bursts, but if this were the cause we would expect to find FRBs towards variable stars (ones with fluctuating brightness) in our galaxy, which is not the case.

White dwarf merger

When two white dwarfs merge its possible they can combine into a larger, rapidly spinning white dwarf. This event could emit radiation from the poles consistent with FRBs and, if this is proved correct, it could indicate an association between FRBs and supernovae.

Neutron star collision

Ultra-dense stellar known as neutron stars could collide and release huge bursts of radiation before they merge – this event is already thought to be a cause of high-energy bursts known as Gamma Ray Bursts (GRBs), and could also be the cause of FRBs.

Blitzar

Some neutron stars are regarded as being ‘supramassive’, which means they are so massive they should have already collapsed into a black hole but their rapid rotation keeps them alive. When they do suddenly collapse they release an intense burst of radio waves known as a blitzar, and within this emission FRBs could also be residing.

Fascinating article, but I'm leaning toward some exotic force we don't fully understand as opposed to ET. What makes anyone think another civilization would develop radio for communications?
Advanced civilizations would use 'spooky attraction' to communicate instantly as all points in the universe are connected. When we get to the point where we have something on that level, ET shouldn't be so elusive.
On a side note, be careful when you Google White dwarf merger
